[0044] Working principle: The present invention can improve storage efficiency and protect fragile items by distinguishing and storing fragile items from ordinary items. At the same time, the present invention can increase storage space by deformation, so that large express items can be placed and the workload can be reduced. In addition, the present invention can directly transport express items to the inside of a loading vehicle, making it convenient for people to load express items. A plurality of express parcels are transmitted through the conveyor belt mechanism 1, and the express parcels on the conveyor belt mechanism 1 are observed through an external camera, so as to determine whether the express parcels are fragile items or ordinary items; When the express is pushed, the fourth screw moving mechanism 315, the telescopic frame 316 and the shovel head 317 are driven to move up and down by the extension and contraction of the second electric cylinder 314, so that the shovel head 317 can push the express at different heights; the servo motor B of the fourth screw moving mechanism 315 drives the screw D of the fourth screw moving mechanism 315 to rotate, thereby driving the slider D of the fourth screw moving mechanism 315 to move, thereby driving the telescopic frame 316 and the shovel head 317 to move to the express at the corresponding position, and then the telescopic frame 316 is extended to drive the shovel head 317 to move to the side of the express, and then the motor on the telescopic frame 316 drives the shovel head 317 to rotate, so that the shovel head 317 contacts the express, and then the telescopic frame 316 is extended to drive the shovel head 317 to move, so that the shovel head 317 drives the express to move to the vicinity of the equipment, so as to facilitate the storage of the express; When it is necessary to load ordinary express from the conveyor belt mechanism 1 onto the device, first, the first swing rod 205 is driven to swing by the first motor 207, so that the first swing rod 205 moves the rods on both sides of the rectangular box 201 along the slide grooves on both sides of the rectangular frame 202, thereby driving the rectangular box 201 to move out of the rectangular frame 202, and at the same time, driving the cylindrical gear 204 to move. When the cylindrical gear 204 moves to mesh with the spur rack 203, the first swing rod 205 is driven by the first motor 207 to continue to swing, thereby driving the cylindrical gear 204 to continue to move, so that the cylindrical gear 204 rotates, and then drives the rectangular box 201 to rotate, so that the rectangular box 201 is tilted at a certain angle. At this moment, the opening above the rectangular box 201 is more convenient for the express on the conveyor belt mechanism 1 to fall into the interior of the rectangular box 201; In order to better preserve the fragile express, it is necessary to place the fragile express in different storage boxes 218 in a relatively neat manner. After the express is moved to the small conveyor belt mechanism 213, the motor on the connecting bracket 212 drives the small conveyor belt mechanism 213 to rotate, so that the small conveyor belt mechanism 213 is tilted at a certain angle, which is convenient for the express to fall into the storage boxes 218 at different heights; at the same time, the motor on the supporting bottom plate 210 drives the lead screw D of the first lead screw moving mechanism 211 to rotate, thereby driving the slider D of the first lead screw moving mechanism 211 to move, thereby driving the connecting bracket 212 and the small conveyor belt mechanism 213 to move, thereby facilitating the more neat storage of the express in the storage box 218, and better utilizing the storage space inside the storage box 218; The third motor 217 is driven to swing by one of the second swinging rods 216, so as to push a storage box 218 at the corresponding position to move out of the rectangular frame 214, so as to facilitate the fragile express on the small conveyor belt mechanism 213 to fall into the storage box 218. Since a support plate 219 is slidably installed inside the storage box 218, and a spring 220 is fixedly connected to the lower end surface of the support plate 219, the spring 220 and the support plate 219 can reduce the shock of the express placed in the storage box 218 to prevent the express from being damaged. If it is necessary to place a larger object, first, the third swing rod 310 is driven to swing by the motor on the supporting square plate 308, thereby driving the connecting block 311 to descend, thereby driving the suction cup 312 to be adsorbed on the square support plate 301 to prevent the supporting square plate 308 from moving; the motor on one of the third screw moving mechanisms 309 drives the screws C of the two third screw moving mechanisms 309 to rotate, thereby driving the sliders C of the two third screw moving mechanisms 309 to move, thereby driving the square plate 208 and the square bottom plate 221 to move in opposite directions, thereby increasing the space between the square plate 208 and the square bottom plate 221, thereby making it easier for people to lift and place larger objects on the equipment; If the item is too large and needs to be further expanded, the second motor 209 drives the rectangular frame 202 to rotate along the arc-shaped slide groove on the square plate 208, and at the same time, the fourth motor 222 drives the rectangular frame 214 to rotate along the arc-shaped slide groove on the square bottom plate 221, thereby expanding the space between the rectangular frame 202 and the rectangular frame 214, so as to facilitate the placement of larger items. When assembling goods, at this moment, because the bucket of the loading truck is too long, under normal circumstances, it is necessary to manually use a cart to take the express from the ground, then push the cart onto the loading truck, and then manually take the express from the cart and put it on the loading truck. The present invention drives the entire device to move through the first electric wheel 302; when the goods need to be unloaded, at this moment the first electric wheel 302 is in a fixed state, and the connecting plate 303 is extended and retracted to push the square support plate 301 to lift, so that the entire device on the square support plate 301 is lifted to a position where it can be moved to the loading truck, and then the motor D of the second screw moving mechanism 305 drives the screw B of the second screw moving mechanism 305 to rotate, thereby driving the two sliders B of the second screw moving mechanism 305 to move, thereby driving the two sliding rods 306 to release the second electric wheel 307, so that it is convenient for the second electric wheel 307 to drive the supporting square plate 308 and other equipment on the supporting square plate 308 to move to the loading and unloading truck, thereby reducing the labor of manual handling; When unloading fragile items in the storage box 218, the opening and closing door 215 is opened manually, and the second swing rod 216 drives the third motor 217 to swing, so that the third motor 217 drives the storage box 218 to move out of the rectangular frame 214 from the end of the opening and closing door 215, making it convenient for manual removal of the express delivery in the storage box 218.

At this moment, the opening above the rectangular box (201) makes it easier for the express on the conveyor belt mechanism (1) to fall into the interior of the rectangular box (201); S4: The small conveyor belt mechanism (213) is driven to rotate by the motor on the connecting bracket (212), so that the small conveyor belt mechanism (213) is tilted at a certain angle, so that the express delivery can be dropped into the storage boxes (218) at different heights; at the same time, the motor on the supporting bottom plate (210) drives the lead screw D of the first lead screw moving mechanism (211) to rotate, thereby driving the slider D of the first lead screw moving mechanism (211) to move, thereby driving the connecting bracket (212) and the small conveyor belt mechanism (213) to move, so that the express delivery can be stored more neatly inside the storage box (218), and the storage space inside the storage box (218) can be better utilized; S5: When a larger object needs to be placed, first, the third swing rod (310) is driven to swing by the motor on the supporting square plate (308), thereby driving the connecting block (311) to descend, thereby driving the suction cup (312) to be adsorbed on the square supporting plate (301) to prevent the supporting square plate (308) from moving; the motor on one of the third screw moving mechanisms (309) drives the screws C of the two third screw moving mechanisms (309) to rotate, thereby driving the sliders C of the two third screw moving mechanisms (309) to move, thereby driving the square plate (208) and the square bottom plate (221) to move toward each other. The rectangular frame (202) and the rectangular bottom plate (221) are moved in opposite directions, thereby increasing the space between the square plate (208) and the square bottom plate (221), thereby making it easier for people to lift and place larger items on the device; if the item is too large and more space is needed, the second motor (209) drives the rectangular frame (202) to rotate along the arc-shaped slide groove on the square plate (208), and at the same time, the fourth motor (222) drives the rectangular frame (214) to rotate along the arc-shaped slide groove on the square bottom plate (221), thereby expanding the space between the rectangular frame (202) and the rectangular frame (214), thereby making it easier to place larger items; S6: The connecting plate (303) is extended and retracted to push the square support plate (301) to lift up, so that the equipment on the square support plate (301) is lifted up as a whole to a position where it can be moved to a loading vehicle. Subsequently, the motor D of the second screw moving mechanism (305) drives the screw B of the second screw moving mechanism (305) to rotate, thereby driving the two sliders B of the second screw moving mechanism (305) to move, thereby driving the two sliding rods (306) to release the second electric wheel (307), so that the second electric wheel (307) drives the supporting square plate (308) and other equipment on the supporting square plate (308) to move to the loading and unloading vehicle, thereby reducing the labor of manual handling; S7: The express is then removed from the device manually.
